OBJECTIVE To evaluate the effects of ropinirole on selected nonmotor symptoms of Parkinson's disease (PD), including anxiety, depressive symptoms, sleep disturbances/excessive daytime sleepiness, and sexual functions. METHODS Forty-four consecutive PD patients with or without motor complications (MC+ group and MC- group, respectively); 6-month prospective… (More)
We demonstrate the effect of deep brain stimulation of the ventral intermediate thalamic nucleus on intractable action tremor, in a 72-year-old man suffering from neuropathy associated with monoclonal gammopathy.
PURPOSE Multiple system atrophy (MSA) is a rare neurodegenerative disease that remains poorly understood, and the diagnosis of MSA continues to be challenging. We endeavored to improve the diagnostic process and understanding of in vivo characteristics of MSA by diffusion tensor imaging (DTI). MATERIALS AND METHODS Twenty MSA subjects, ten parkinsonian… (More)
It is currently unknown whether speech and limb motor effectors in Parkinson's disease (PD) are controlled by similar underlying brain processes. Based on computerized objective analysis, the aim of this study was to evaluate potential correlation between speech and mechanical tests of upper limb motor function. Speech and upper limb motor tests were… (More)
INTRODUCTION Timed performance tests were introduced to overcome the disadvantages of subjective evaluation of bradykinesia in Parkinson's disease (PD). We aimed to verify their discriminative properties and compare them with the motion capture analysis of finger tapping. METHODS We included 22 PD patients (10 M, 12 F), mean age 64 (range 48-82) yrs,… (More)
BACKGROUND Falls are a common complication of advancing Parkinson's disease (PD). Although numerous risk factors are known, reliable predictors of future falls are still lacking. The objective of this prospective study was to investigate clinical and instrumented tests of balance and gait in both OFF and ON medication states and to verify their utility in… (More)
The Grooved Pegboard Test (GPT) was conceived as a test of manual dexterity, upper-limb motor speed, and hand-eye coordination. The aim of our study was to test the componential structure of the GPT on an archetypal model of motor impairment, Parkinson's disease (PD). A total of 45 PD patients (33 males, 12 females; age M = 67, range = 49-81; PD duration M… (More)
